Condemning Colonization: Abraham Lincolnâs Rejected Proposal for a Central American Colony
This article focuses on a proposal by Abraham Lincoln to settle freed African Americans in Central American countries. The backlash from several countries reveals that other countries besides the warring United States were also struggling with reconciling racial issues. This also reveals how interwoven racial issues were with political crises during the Civil War because it not only effected domestic policies but also international relations
German Mission in Abyssinia: Wilhelm Staiger from Baden, 1835â1904
This article deals with the story of the Christian mission among the Jews of Ethiopia during the 1860s as related in the memoirs of the German missionary, Wilhelm Staiger, publicised here for the first time. Staiger who had, together with scores of other European missionaries, become caught up in the political turmoil between Great Britain and Teodoros, King of Ethiopia, describes the affair in the first person
Fine-needle Aspiration Biopsy For Breast Lesions: A Comparison Between Two Devices For Obtaining Cytological Samples
Context and Objective: Fine-needle aspiration biopsy has been accepted worldwide for breast lesions. However, some questions remain, including the appropriateness of the puncture method. The objective of this work was to compare aspirates obtained by the auto-vacuum device and by the syringe pistol holder. Design and Setting: Randomized trial for validation of diagnostic method, at Hospital das Clinicas do Universidade Federal de GoiĂĄs and Hospital AraĂșjo Jorge, GoiĂąnio. Methods: 351 patients presenting breast lumps underwent fine-needle aspiration biopsy, either with the auto-vacuum device or the syringe pistol holder. A single cytopathologist analyzed all of the cytology slides. The rates of insufficient material, cellularity, cell distortion and background hemorrhage were evaluated. Results: The percentages of insufficient material were 16% and 22% (p = 0.18), for the auto-vacuum and pistol aspirates, respectively. Good cellularity was seen in 34% of autovacuum and 29% of pistol samples (p = 0.4). Cell distortion was seen in 31 and 26 cases, respectively (p = 07). Background hemorrhage occurred in 63 (35%) and 54 cases (31%) (p = 0.2), for auto-vacuum and pistol. The sensitivity was 88% and 86%; specificity 99% and 100%, positive predictive value 96% and and 100%, negative predictive value 96% and 95% and total occuracy 76% and 75% for the auto-vacuum and pistol, respectively. Conclusion: The results obtained from the two fine-needle aspiration biopsy methods were equivalent. Therefore, the auto-vacuum device is a good option for obtaining aspirates for cytology.1236271276Catania, S., Ciatto, S., Breast cytology: Instruments and technique (1992) Breast Cytology in Clinical Practice, pp. 11-60. , In: Ciatto S, editor.

Transnational Surfistas and the Development of Nicaraguaâs Emerald Coast
This article weaves together data from the Nicaraguan Institute of Tourism (INTUR), online mainstream media sources, and surfing magazines, to tell the story of the development of the Emerald Coast, a historically overlooked periphery in southwestern Nicaragua that evolved into one of the countryâs most high-profile and sought-after tourism destinations. The argument is that it is impossible to effectively explain the development of the Emerald Coast without first understanding the role surfing played in this phenomenon. This also serves to contextualize these foreign surfers as part of another wave of transnational engagement with Nicaragua, a country that has long been impacted by foreign actors from the United States and Europe. The convergence of opportunity â cultural, economic, and political forces â and environment facilitated the rise of Nicaraguaâs surf tourism industry, which in turn engendered subsequent forms of leisure tourism. Over the course of three decades, this new industry shifted the economic focus of Nicaragua, as tourism became the leading contributor, in terms of revenue, to Nicaraguaâs overall Gross Domestic Product (GDP). This article places foreign surfers at the center of this phenomenon by telling the story of the development and evolution of the Emerald Coast through the lens of surfing
Empire at Play: The United Statesâ Cultural Influence on Nicaraguaâs National Sportsâ Identity
âEmpire at Playâ seeks to contextualize the inception of a Nicaraguan surfing subculture in the first decade of the twenty-first century by situating it within the broader scope of the United Statesâ influence on Nicaraguaâs sporting history. By weaving together primary and secondary sources, as well as oral histories from expatriate surfers, Nicaraguan nationals, and members from the local indigenous communities, this article shows how international actors from the United States introduced Nicaragua to three of their major sports: baseball, boxing, and surfingâall of which became part of Nicaraguaâs cultural identity. As these three sports grew in popularity domestically, so too did the infrastructure capable of hosting major international events, subsequently garnering international recognition as authentically Nicaraguan sports. While these activities are merely extracurricular in and of themselves, examining their proliferation as part of the expansion of American empire in the twentieth century helps to underscore the varying forms of American imperialism that facilitated each sportâs introduction and popularizationâsurfing being the most recent of the three
Initial Plant Growth in Sand Mine Spoil Amended with Peat Moss and Fertilizer Under Greenhouse Conditions: Potential Species for Use in Reclamation
The Great Lakes Basin exhibits the largest collection of freshwater sand dunes in the world. Sand dunes are ecologically important and support a unique assemblage of flora and fauna. Sand dunes are also economically valuable. However, when sand dunes are mined, soil quality is drastically reduced. Therefore, soil quality improvements followed by revegetation maybe necessary for successful reclamation. This study evaluates the germination and initial growth of 2 legume species, sundial lupine (Lupinus perennis) and Illinois bundleflower (Desmanthus illinoensis), and 2 warm-season grass species, Indian grass (Sorghastrum nutans) and little bluestem (Schizachyrium scoparium), in the presence of 2 soil amendments (inorganic fertilizer and sphagnum peat moss) added to spoil from a local sand mine. We sowed species in pots and propagated them under greenhouse conditions. Results indicate that sundial lupine and Illinois bundleflower exhibited the greatest germination and growth among species. Peat moss had the greatest overall impact on germination and growth while the addition of fertilizer positively affected initial growth. Based on these results, sundial lupine is recognized as a primary candidate for sand mine reclamation, while Illinois bundleflower is also recommended as an appropriate species for revegetation efforts. We recommend using soil amendments that are functionally equivalent to peat in increasing soil water holding capacity. We further suggest that fertilization may be accomplished by including legumes in plant species mixes used for revegetation. Results presented here may help to identify appropriate species and soil amendments for the reclamation of former sand mines or restoration of freshwater sand dunes
âThey are not of our raceâ: Northern Republican Senators, Anti-Cuban Prejudices, and the American Opposition to Cuban Acquisition in 1859
Which factors do U.S. statesmen consider when incorporating new U.S. territories? Which populations and territories are deemed compatible with the project of the American nation, and which arenât? At the U.S. Congress in 1859, upon the presentation of Senate Bill 497, U.S. Senators were debating whether to allocate a millionaire sum of money to President James Buchanan in order to acquire Cuba. The Congress debates were divided between Northern Republican and Southern Democrat Senators, of whom the former consistently opposed the annexation of Cuba. The reasons for opposition were various, but this study focuses on the senatorâs suggestion that the Cuban population was unfit for self-government. By analyzing the speeches of several Northern Republican Senators, this study analyses how religious, cultural, and racial prejudices against Cubans deterred Americans from annexation. This analysis ultimately reveals that the anti-slavery convictions of Northern Republican Senators extended only to territories where the white American population could predominate, which they deemed impossible in Cuba
Misleading Presentations of Malignant Breast Diseases â Role of Clinical Cytology
We described two examples with misleading presentations to draw attention to the role of clinical cytology as a part of multidisciplinary approach to breast lesions. In the first case â Pagetâs disease of the nipple, there was no obvious clinical and radiological evidence of breast cancer, while the second case â primary non-Hodgkin lymphoma of the breast imitated advanced breast carcinoma. The question is whether accurate and fast diagnoses can be made without cytological examinations. It must be kept in mind that first-hand clinical information and contact with the patient is necessary in rendering accurate cytological diagnoses
DIPL 6801 US Foreign Policy in Latin America and the Caribbean
This seminar examines the major foreign policy doctrines applied by the United States in Latin America from the Monroe Doctrine through the Good Neighbor Policy and the Alliance for Progress until the recent agendas combining the âWar on Terrorâ and âFree Trade.â We will ask questions such as how US policy is shaped, why it has changed over time, which policies are most effective in securing mutually beneficial relationships, and what the policy options are with regard to key issues such as trade, immigration, drugs, and democracy promotion. The seminar focuses on developing analytical, writing, and presentational skills
